If a player has a sevens to roll ratio of 8, and the standard is 6, what is the edge a player has.

I hope Im asking the right question by assuming that the seven rolls up 6 in 36 rolls, but this player avereges 8 in 36 rolls over 15K rolls.

Not saying it can be done, but assuming you're not betting the Dark Side, wouldn't the idea be to be able to have a higher SRR for the come-out, and a lower one once a Point is established? (And the reverse if you are betting the Dark.)

Great! A 7 shooter. One better than a 6 shooter.
You mean he has a 4.5 SRR (36/8)
EV (# of 7s) over 15k rolls would be 2500
standard deviations is about 45.6
3,333 7s in that time would be 4.5 SRR (average 8 in 36 rolls or a 22.2% probability)
833 difference from average or about 18SDs away from the average.
Excellent control or very biased dice or non-legal casino throws or boths IMO

He should be able, with the right bankroll, to make a lot of $$$ with Lay bets and 3way7 bet
and even the don't lay odds too once you get passed the come out roll. (less variance)


You can get WinCraps (shareware to use) and change the numbers in it like I did.
Easy and it does all the math correctly for you too.





Is this from actual casino dice rolls??
if yes, should be very easy to find a large bankroll

Good Luck

i ran mine from my smart craps


Win/loss rates:
*** Expectation: 5.247794%
(total of all wins and losses, divided by the total of all bets made)
Average earnings/loss per throw: $2.130041
Average earnings/loss per betting event: $4.408658
Average earnings/loss per hand: $19.366881
Average earnings/loss per hour: $213.004128
Average # of bets/hour: 48.3
(assumes 100 throws per hour)

Simulation statistics:
Intended # of rounds in simulation: 10,000,000
Actual # of rounds completed: 10,000,009
Each round is a: throw (roll of the dice)
Random seed: 12345
Start time for simulation: Thu May 30 22:12:37 2013
End time for simulation: Thu May 30 22:12:53 2013
Elapsed simulation time: 00:00:16
Total # of hands: 1,099,838
Average # of throws/hand: 9.09
Longest hand (in throws): 113
50% of hands are of throw length 7.33 or more (median value)
5% of hands are of throw length 25.02 or more
1% of hands are of throw length 37.39 or more
Inferred probability of hand ending per round (seven out): 12.2014%
Distribution table of hands by length (1,099,838 hands in total):


My srr is 8.05 , that is on my practice table at home. i am sure it is not
exactly the same at a casino. Based on this if you have a SRR of 7 it would give
you about 4.55% advantage.

That means you have about a 3% advantage on the 6 & 8 and no advantage on
the 5 & 9 and no advantage on the field if they pay only double on the 2 & 12.
